This  is  a  digital  copy  of  a  book  that  was  preserved  for  generations  on  library  shelves  before  it  was  carefully  scanned  by  Google  as  part  of  a  project 

to  make  the  world's  books  discoverable  online. 

It  has  survived  long  enough  for  the  copyright  to  expire  and  the  book  to  enter  the  public  domain.  A  public  domain  book  is  one  that  was  never  subject 

to  copyright  or  whose  legal  copyright  term  has  expired.  Whether  a  book  is  in  the  public  domain  may  vary  country  to  country.  Public  domain  books 

are  our  gateways  to  the  past,  representing  a  wealth  of  history,  culture  and  knowledge  that's  often  difficult  to  discover.

INTRODUCTION* 


The  study  of  mineral  names  is  an  interesting  one,  not  only  from  the 
mineralogist's  point  of  view,  as  affording  an  insight  into  the  growth  and 
development  of  this  branch  of  science,  but  also  to  the  student  of  human 
nature,  for  many  traits  of  character  are  shown  in  the  various  considerations 
which  have  determined  the  particular  name  to  be  adopted. 

We  sometimes  find  as  the  reason  for  a  name  the  simple  idea  of  distin- 
guishing the  thing  itself;  but  this  is  not  the  most  common  reason.  To  do 
honor  to  some  person  who  may  perhaps  be  pleased  or  flattered  by  the  atten- 
tion, or  to  immortalize  some  place,  often  otherwise  obscure  or  unknown,  is 
a  much  more  common  reason.  Names  have  been  given  to  commemorate 
battle-fields,  to  sneer  at  the  work  of  earlier  investigators,  and  as  a  tribute 
to  feminine  loveliness.  In  short  the  whole  round  of  human  passions  has 
been  gone  over  in  the  manufacture  of  these  words,  which  are  purely  scien- 
tific in  their  uses,  and  for  the  making  of  which  scientific  methods  might 
well  have  been  employed.  The  subject  has  also  no  little  interest  from  the 
philological  side,  and  these  names  deserve  stady  if  only  as  part  of  our 
language. 

One  of  the  most  noticeable  things  about  mineral  names  is  the  lack  of 
uniformity  in  their  terminations.  While  the  large  majority  of  them  end 
in  -ite,  there  are  many  in  -ine,  while  -ane,  -ase,  -ose,  and  several  others 
have  been  often  used.  It  is  to  be  regretted  that  the  termination  -ite  has 
not  been  universally  adopted,  for  it  has  been  so  far  adopted  as  to  be  the 
generally  accepted  one  for  such  names.  It  has  the  sanction  of  antiquity, 
for  it  was  used  by  the  old  Greek  writers  in  the  forms  -ites  or  -itis,  as  in 
ai/iariTTfi,  'hematite,' and  dXa/Saaririi,  'alabaster.'  Such  forms  were 
also  used  by  the  Romans,  and  we  have  in  Pliny  siderites,  Modestone,* 
steatitis,  'soapstone,'  molochites,  'malachite,'  and  many  others.  These 
forms  are  undoubtedly  the  source  of  the  termination  -ite  now  in  use,  as 
they  are  the  earliest  known  terminations.  Such  names  were  given  by  the 
ancients  as  noting  some  property  or  use  of  the  mineral,  or  sometimes  desig 

*  Much  of  this  introduction  is  to  be  found  in  my  paper  on  *  The  Origin  and  History 
of  MinenUogical  Names,*  read  before  the  New  Yoric  Academy  of  Sciences  on  January 
25,  1898,  and  published  in  vol.  xi,  pp.  49  to  57,  of  its  Transactions.

nating  its  source,  or  the  locality  from  which  it  was  derived;  as  uayv^rts, 
a  mineral  from  Magnesia.  Or,  to  speak  of  those  already  mentioned, 
aiudrirrfS  is  a  mineral  resembling  blood,  so  called  from  the  color  of  its 
powder;  dXaflaariTiS,  a  mineral  from  which  a  vessel  called  an  alabastron 
was  cut;  siderites,  from  aidrfpo^,  'iron,'  because  it  contains  it;  steatitis, 
from  orearoS,  *of  fat,'  because  it  feels  greasy;  and  molochites,  from 
ijiaXdxv*  *  mallows,'  alluding  to  its  green  color.  In  the  5th  edition  of  his 
great  work  on  Mineralogy,  Prof.  J.  D.  Dana  makes  an  attempt  at  uniform- 
ity of  nomenclature  by  changing  the  terminations  of  many  names  into  ite, 
particularly  those  ending  in  -ine,  only  leaving  those  unchanged  which  had 
come  into  too  general  use  in  the  language  to  be  so  treated.  So  we  have 
galenite,  alabandite,  pyrrhotite,  and  periclasite,  instead  of  galena,  alaban- 
dine,  pyrrhotine,  and  periclase.  These  changes  have  been  generally 
adopted,  and  are  all  in  the  right  direction. 

In  1876  Prof.  C.  U.  Shepard  published  a  '  Catalogue  of  Minerals  found 
within  about  75  miles  of  Amherst  College,  Mass.,'  in  which  he  proposed 
that  the  names  of  all  acknowledged  mineral  species,  except  those  of  the 
elements  and  a  very  few  more,  shall  uniformly  end  in  -ite,  and  that  the 
termination  -ine  shall  as  uniformly  be  used  for  all  variety  names,  and  those 
whose  specific  character  is  not  fully  settled.  Accordingly,  he  gives  us 
gypsite,  serpentite,  wadite,  orthoclasite,  spodumenite,  epidotite,  and  many 
similar  changes,  while  marmolite,  picrolite,  nacrite,  and  others  are  made 
to  end  in  ine,  marmoline,  picroline,  nacrine.  It  is  hardly  necessary  to  say 
that  these  suggestions  have  not-been  generally  or  fully  accepted. 

The  use  of  the  termination  -lite,  in  German  -lith,  from  the  Greek  \iSoi, 
*&  stone,'  ought  here  to  be  mentioned,  as  it  was  a  genuine  attempt  to  intro 
duce  a  distinguishing  mark  for  mineral  names,  which,  if  successful,  would 
have  been  of  great  benefit  to  mineral  nomenclature,  as  bringing  in  the 
desirable  element  of  uniformity.  This  also  comes  from  antiquity,  being 
found  in  the  Greek.  But  it  never  came  into  general  use,  and  in  later  years 
is  seldom  used  except  for  euphony.  There  is  an  erroneous  impression 
that  the  termination  -ite  is  derived  from  this,  which,  as  we  have  seen,  is 
not  the  case,  as  it  is  a  much  older  form. 

As  all  scientific  works  were  written  in  Latin  up  to  a  very  recent  date, 
and  as  there  was  no  chemistry  to  show  differences  in  composition,  there 
was  no  real  progress  in  mineralogy.  External  characters  alone  were  used 
as  means  of  distinguishing  minerals  from  each  other,  and  those  that  looked 
alike  must  necessarily  be  classed  together.  Pliny's  names  were  sufficient 
for  all  the  uses  of  the  science  down  to  the  sixteenth  century.  There  was 
hai-dly  a  name  added,  even  by  Agricola,  whose  large  works  were  published 
1629  to  1546.    The  name  fluor  is  perhaps  his  only  new  one,  and  that  he

probably  (lid  not  originate,  but  took  from  the  vocabulary  of  the  furnace- 
men, who  used  fluor-spar  in  smelting  their  ores.  Certain  minerals  in  general 
use  had  their  common  names  in  various  languages,  but  there  were  few  of 
them. 

Several  attempts  have  been  made  to  give  systematic  names  to  minerals 
on  some  such  principle  as  is  used  in  other  branches  of  natural  science,  but 
not  one  of  them  has  been  generally  ((Qopted,  and  all  have  by  degrees  been 
dropped.  One  of  the  earliest  of  these  was  by  Sir  John  Hill,  in  his  *  History 
of  Fossils,'  London,  1748.  He  divides  minerals  into  numbered  series, 
classes,  and  orders,  and  under  these  into  named  genera  and  species.  His 
genus  names  are  many  of  them  new,  but  are  sometimes  older  names  modi- 
fled  to  suit  his  system.  For  instance,  Marmora,  for  the  marbles.  A  good 
example  of  his  new  names,  and  also  of  the  way  tn  which  species  were 
multiplied  when  only  external  characteristics  were  considered,  is  in  the 
order  of  Inflammables.  The  8d  class  is  called  Phlogonise,  and  under  this 
we  have  as  the  1st  genus,  Pyricubia,  and  under  this  two  species:  1st, 
Pyricubium  maximum  foliaceum,  and  2d,  Pyricubium  solidum  minus. 
The  flrst  of  these  species  is  simply  those  cubical  crystals  of  iron  pyrites 
which  are  striated  by  an  oscillation  towanl  a  hemitetrahexahedron,  and 
the  second  is  the  unstriated  crystals  of  the  same.  Octahedral  pjrrite  is 
made  another  genus,  and  dodecahedral  is  still  another.  Several  more 
genera  are  made  trom  what  is  now  the  one  species.  This  system  never 
came  into  general  use,  and  Hill  himself  gives  it  up  and  adopts  one  much 
more  simple  in  his  later  work  entitled  'Fossils  Arranged  according  to 
their  Obvious  Characters,'  London,  1771. 

In  1820  Prof.  Mohs  brought  out  a  small  book  entitled  '  The  Characters 
of  the  Classes,  Orders,  Genera,  and  Species;  or  the  Characteristic  of  the 
Natural  History  System  of  Mineralogy.  Intended  to  enable  students  to 
discriminate  minerals  on  principles  similar  to  those  of  Botany  and  Qeology.' 
This  system  is  more  fully  presented  in  his  larger  work  of  1822-4,  trans- 
lated by  Haidinger  in  1825.  He  uses  genus  and  species  names  for  each 
mineral,  and  sometimes  adds  a  third  for  more  exact  distinction.  Under 
the  genus  garnet  he  gives  Pyramidal  Garnet,  or  idocrase;  Dodecahedral 
Garnet,  or  true  garnet;  and  Prismatoidal  Garnet,  or  staurolite.  Dioptase 
liecomes  Rhombohedral  Emerald- Malachite.  This  system  was  quite  popu- 
lar  for  a  time,  and  had  several  imitators.  Prof.  C.  U.  Shepard  adopts 
Mohs's  system,  and  in  the  flrst  edition  of  his  mineralogy,  1882-5,  he  not 
only  uses  his  names,  but  extends  the  system  still  further.  He,  however, 
gives  flrst  the  common  or  trivial  names,  as  they  are  called,  and  always  uses 
them  in  speaking  of  species.  Microlite  is  the  one  new  species  of  his  own 
noted  in  this  book,  which  under  the  system  he  calls  Octahedral  Tungstic- 


X  INTRODUCTION 

'Baryte,  and  similar  names  are  carried  all  the  way  through.    None  of  these 
names  are  mentioned  in  his  third  edition,  1852-7. 

In  1836  Prof,  J.  D.  Dana  read  a  paper  before  the  New  York  Lyceum 
of  Natural  History,  entitled  '  A  New  Mineral  Nomenclature/  in  which  he 
presents  a  complete  arrangement  according  to  the  Natural  History  method, 
and  gives  some  very  good  reasons  for  its  adoption.    This  system  is  carried 
out  in  full  in  the  first  edition,  1837,  of  his  Mineralogy.    He  uses  in  general 
two  names  for  each  mineral,  as  Andalusius  prismaticus  for  andalusite,  but 
he  gives  the  common  name  first  in  all  cases.    In  his  second  edition,  1844^ 
he  retains  these  Latin  names  as  the  scientific  ones,  and  as  necessary  to  *  a 
systematic  idea  of  the  science,'  but  adds,  p.  135,  'the  shorter  trivial  names 
should  however  be  retained,  as  more  convenient  for  common  use.'    In  the 
third  edition,  1850.  however.  Prof.  Dana  discards  the  whole  system,  not 
even  retaining  the  names  as  synonyms.     A  system  of  arrangement  is 
adopted  that  was  understood  to  be  temporary,  while  at  the  end  of  the  work 
a  chemical  classification  is  suggested.    In  the  later  editions  this  last  has 
been  perfected,  and  we  now  have  an  arrangement  easy  of  reference  and 
answering  all  purposes  of  classification,  but  from  which  all  traces  of  the 
double  Latinized  forms  of  the  Natural  History  methods  have  disappeared. 
This  or  some  similar  system  is  now  generally  followed  by  writers  on  miner- 
alogy, much  to  the  satisfaction  of  those  who  use  their  works.     In  1847 
Glocker  published  his  work  entitled  '  Gtenerum  et  Specierum  Mineralium 
Synopsis.'    This  is  perhaps  the  most  successful  attempt  at  a  systematic 
nomenclature  that  has  been  made.    He  uses  in  general  a  Latinized  form  of 
the  common  name  for  the  name  of  each  species,  with  some  descriptive 
word  added.    For  varieties  he  adds  a  third  word,  as  is  common  in  other 
branches  of  natural  history.     For  instance,  imder  Granatus,  garnet,  he 
gives  three  species:   1st,  Granatus  nobilis,  precious  garnet;  2d,  Granatus- 
hyacinthinus,    cinnamon   garnet;    and  3d,    Granatus  vulgaris,  common 
garnet,  and  under  the  latter  he  uses  for  varieties  the  terminations  fuscus,. 
niger,  viridis,  flavus,  and  albidus.    The  work  is  in  Latin,  thus  going  back 
to  the  style  of  the  scientific  books  of  the  last  century.     Recently  Prof.  T. 
Sterry  Hunt  has  devised  a  new  Natural  System,  suggested  indeed  as  early 
as  1853,  but  as  he.  gives  few  new  species  names  a  discussion  of  it  would  be 
out  of  place  here.    His  work  is,  however,  exceedingly  interesting,  and  will 
well  repay  examination  by  those  who  care  to  go  further  into  that  side  of 
che  general  subject. 

In  1728  Dr.  John  Woodward  published  a  work  entitled  '  Fossils  of  all 
Rinds  Digested  into  a  Method,  Suitable  to  their  Mutual  Relations  and 
Affinity,'  but  it  is  a  description  from  external  characters  only,  and  can 
hardly  be  called  a  scientific  treatise.    The  first  one  that  really  deserve8> 


INTRODUCTION 

such  a  name  is  by  the  Swedish  mineralogist  Wallerius,  in  1747,  which  is 
arranged  on  a  scientific  plan,  and  gives  us  the  earliest  systematic  descrip- 
tion of  minerals.  Cronstedt,  another  Swedish  chemist,  ten  years  later  gave 
us  a  work  of  much  greater  value,  as  he  brought  in  chemical  relations,  as 
far  as  was  possible  in  the  crude  state  of  that  science.  But  few  new  names 
were  added,  for  the  study  was  still  largely  from  the  external  side,  and  new 
species  could  not  be  recognized.  With  the  discovery  of  oxygen  in  1776, 
and  the  real  beginning  of  the  science  of  chemistry,  a  more  correct  basis  for 
the  differentiation  of  mineral  species  was  found.  This  was  aided  by  the 
application  of  scientific  crystallography,  the  first  edition  of  de  L'Isle's  work 
appearing  in  1772,  and  the  second,  in  four  volumes,  in  1788.  From  this 
date  new  names  were  given  to  minerals  as  the  result  of  more  extended 
research  in  this  branch  of  study,  and  one  of  the  first  of  these  was  prehnite, 
given  by  Werner  to  a  mineral  brought  from  the  Cape  of  Good  Hope  by 
Colonel  Prehn,  and  hence  named  after  him.  Werner  first  announced  the 
name  in  his  lectures  in  1788,  as  he  himself  states  later,  but  it  was  not  pub- 
lished for  several  years.  In  1789  there  is  an  article  in  the  Journal  de 
Physique,  by  Sage,  objecting  to  the  use  of  names  of  persons  for  minerals, 
the  text  for  which  is  this  name  of  Werner's.  But  the  name  has  kept  its 
place,  and  is  now  the  accepted  one  for  the  species.  Other  names,  given 
about  the  same  time  after  persons,  are  witherite,  after  Dr.  Withering,  who 
first  described  it,  and  torberite,  later  changed  to  torbemite,  after  Torbem 
Bergmann,  its  first  analyst.  This  latter  mineral  has  gone  through  various 
vicissitudes  as  to  its  name,  and  a  list  of  them,  as  an  illustration,  may  not  be 
out  of  place  here;  they  are  taken  from  the  5th  edition  of  Dana's  Mineral- 
ogy, p.  686:  Mica  viridis,  1772;  Chalkolith,  1788;  Torberite,  1793;  Uran- 
glimmer,  1800;  Torbernit,  1803;  Uranite,  1814;  Uranphyllit,  1820;  Cupro- 
uranit,  1865. 

The  author's  study  of  the  history  of  mineral  names  was  begun  in  the 
interest  of  Murray's  New  English  Dictionary,  where  these  names  are  con- 
sidered as  words  simply,  and  part  of  the  language  as  found  in  books.  The 
information  sought  with  reference  to  each  is  1st,  the  author  of  the  name; 
2d,  the  date  of  its  first  publication;  8d,  a  reference  to  the  original  publica- 
tion; 4th,  its  first  form,  if  different  from  the  one  now  used  by  English 
writers;  6th,  its  derivation;  6th,  the  reason  for  the  name;  7th,  a  short 
description,  sufficient  to  identify  it,  particularly  if  the  name  has  been  used 
for  more  than  one  species  or  variety.  A  good  example  is  Erinite,  a  name 
given  by  W.  Haidinger,  1828,  Ann.  Phil.,  2d,  iv,  154,  from  Erin,  because 
it  was  supposed  to  have  been  found  in  Ireland.  It  is  a  green,  fibrous,  arse- 
niate  of  copper.  This  description  is  necessary  to  distinguish  it  from  Erinite 
of  7.  Thomson,  1886,  Thom.  Min.,  i,  342,  derived  also  from  Erin,  for  the 


XU  INTRODUCTION 

same  reason,  and  properly  so,  for  it  came  from  Ireland.  But  this  is  a 
reddishp  clay-like  mineral  from  the  Giant's  Causeway,  and  probably  does 
not  merit  a  name  at  all. 

Full  information  about  many  naiucs  is  easily  obtained,  and  is  usually 
to  be  found  in  the  last  edition  of  Dana's  Mineralogy,  up  to  1892.  But  with 
reference  to  a  considerable  number  of  names  the  information  wanted  is  not 
easy  to  obtain,  and  in  some  cases  perhaps  it  cannot  be  found  at  all.  When 
it  is  not  given  in  Dana's  Mineralogy,  the  student  may  be  sure  that  he  must 
search  to  find  it.  This  is  particularly  true  of  obsolete  names,  information 
about  which  must  often  be  sought  in  the  earlier  volumes  of  scientific 
journals.  The  first  publication  of  T  Taylar*B  name  killinite  is  in  1818,  in 
vol.  xiii,  p.  4,  of  the  Transactions  of  the  Royal  Irish  Academy,  a  fact  not 
given  in  any  work  on  mineralogy.  There  are  some  names  also  about 
whi&h  very  erroneous  ideas  as  to  derivation  prevail,  and  which  need  cor- 
rection. The  name  chabazite  was  given  in  the  form  chabasie,  by  Bosc 
d Antic,  1780,  Jour.  d'Hist.,  il,  181,  and  is  derived  from  x^^P^^^o^*  the 
name  given  to  one  of  the  stones  mentioned  in  the  Orphic  poem  '  Ilepi 
XiBov,*  The  name  as  we  now  have  it  in  the  poem  is  ;t^^<^Cto?,  and  the 
mineral  should  therefore  have  been  called  chalazite.  Eidd  called  attention 
to  the  blunder  in  1809,  Eidd  Min.,  i,  249;  but  the  original  name  has  held 
its  place.  It  is  but  fair  to  say  that  the  form  x^flo^Z^oi  was  used  in  the 
current  editions  of  the  poem  at  the  time  the  name  was  applied.  The  deri- 
vation of  the  word  datholite  has  often  been  incorrectly  given.  It  is  really 
a  corruption  of  the  original  name  datolith,  given  by  Esmark  in  1806,  from 
ddreojiicxt,  to  divide,  alluding  to  the  granular  structure  of  one  of  its 
varieties,  and  Xtdoi.  Werner  added  the  h  for  no  apparent  reason,  and  the 
changed  form  was  adopted  by  most  authors  until  Prof.  Dana,  in  1868,  un- 
riddled the  matter  and  gave  it  its  correct  form  again.  But  wise  writers 
have  tried  to  find  another  derivation  for  it,  and  one  author  of  note  says  it 
is  from  ddBoi,  which  he  says  means  turbid,  because  the  mineral  is  not 
clear  and  transparent.  A  wiser  one  says  there  is  no  such  Greek  word  as 
ddSoi,  which  is  true,  and  that  it  is  from  the  compound  word  da-BoXXoi, 
meaning  very  turbid,  because  it  is  never  found  in  transparent  crystals, 
which  is  no  more  a  proper  derivation  than  the  other.  The  word  feldspar 
has  been  changed  into  felspar  for  no  better  reason  than  that  the  latter  form 
was  thought  the  right  one.    It  was  used  by  Wallerius  in  his  Mineralogy  % 

of  1747,  p.  65,  in  the  Swedish  form  felt-spat,  meaning  fieldspar.  It  did  not 
originate  with  him  probably,  but  may  have  been  a  popular  name  in  his  time. 
Da  Costa  used  it  in  1757,  Nat.  Hist.  Fossils,  287,  in  the  German  form  feld- 
spath,  and  this  form  was  current  until  1794,  when  we  find  in  Eirwan's 
Mineralogy,  vol.  i,  p.  817,  the  following  note:  'This  name  seems  to  oe 


INTRODUCTION  xiil 

deriyed  from  fels,  a  rock,  it  buing  commouly  found  ia  granites,  and  not 
from  feld,  a  field;  and  hence  I  write  it  thus,  felspar.'  This  assumption  of 
Eirwan  has  been  taken  for  fact  by  all  English  writers,  and  the  corrupt 
form  is  in  very  general  use.  Another  interesting  cose  is  that  of  the  name 
pyroxene,  which  is  popularly  supposed  to  have  been  given,  from  nvp, 
*fire/  and  ^dvoi^  'a  stranger,'  in  the  idea  that  it  is  of  mre  occurrence 
among  volcanic  rocks,  while  in  fact  Hntly  expressly  states,  1801,  HaQy 
Min.,  ii,  64,  that  it  is  very  abundant  among  the  volcanic  matters  of  Vesu- 
vius, Etna,  etc.,  but  is  there  as  a  stranger,  the  name  expressing  that  it 
is  not  in  its  native  place,  but  existed  in  the  nou-volconic  rocks  which 
furnished  the  original  material  of  the  lava. 

Authors  often  omit  giving  the  reason  for  adopting  a  name.  Where  it 
is  on  account  of  some  characteristic  of  the  mineral,  its  author  often  takes 
it  for  granted  that  it  is  as  evident  to  others  as  to  himself.  The  name 
coracite,  J.  L.  L$  Conte,  A.  J.  S..  2d,  iii,  117,  is  a  case  in  point.  Le  Conte 
does  not  give  any  derivation,  but  it  is  the  name  of  a  pitch-black  variety  of 
uraninite,  and  is  probably  derived  from  Kopa^,  a  raven.  A  similar  case  is 
that  of  adinole,  Beud.  Min..  1882,  ii,  126.  No  derivation  is  given,  but  it 
may  easily  be  conjectured  from  the  description  that  it  is  from  ddiyoi,  *  com- 
pact.' But  there  are  other  cases  where  there  is  nothing  suggestive  in  the 
description,  and  even  conjecture  is  at  fault.  Such  conjectures  if  stated  as 
such  are  of  value,  but  to  give  them  as  facts,  as  has  often  been  done,  is  cer- 
tainly a  serious  blunder,  if  not  something  worae.  In  one  of  the  large  dic- 
tionaries we  find  the  name  acanticone  derived  as  follows:  from  'Greek 
ctK^,  point,  drri,  against,  and  kSvo?,  cone.'  This  is  a  mere  guess.  The 
name  was  given  by  B,  J.  d'Andrada,  1800,  Jour,  de  Phys.,  ii,  240,  in  the 
form  akanthicone,  and  is  derived  from  txK(XvbU,  a  gold-finch,  and  kovux, 
powder,  because  the  color  of  the  powdered  mineral  is  yellow.  A  similar 
blunder  is  made  with  the  name  alvite,  so  called  after  one  of  its  localities, 
Alve,  Norway.  lu  the  dictionary  it  is  said  to  be  derived  from  alvus, 
the  belly.  Another  instance  of  a  mistaken  derivation  is  that  of  coreite.  an 
obsolete  synonym  of  agalmatolite,  popularly  supposed  to  be  from  Corea, 
probably  because  agalnutolite  is  from  China,  and  Corea  is  close  by. ,  The 
name  was  given  by  J,  C.  Delamet^ierie  in  1795.  and  he  derives  it  from 
Xoipeioi,  '  of  a  swine,'  because  of  its  greasy  appearance.  He  at  first  calls 
it  koireiite,  but  changed  it  to  koreiite,  and  then  to  koreite,  which  has  since 
been  changed  to  its  present  form,  resembling  one  derived  from  the  name 
Corea.    But  the  name  should  be  choireiite,  commencing  with  eh. 

Sometimes  errors  of  the  compositor  have  failed  of  correction,  and  these 
spurious  words  have  found  their  way  into  later  books  as  real  names.  One 
of  these  is  glorikite,  1859,  Duf.  Min.,  iii,  826,  which  is  an  error  for  glinkite. 


XIV  INTRODUCTION 

Gibsonite,  in  the  1847  edition  of  tbe  same  work,  iii,  761,  is  probably  an 
error  for  gibbsite,  but  this  is  not  so  clear.  Gkiladsite,  galadstite,  and  galad- 
tite  are  all  printer's  errors  for  galaktite. 

A  curious  case  of  this  sort  is  seen  in  the  various  forms  of  the  word 
didymite.  It  was  announced  by  G,  E.  Schaufhautl  in  1843  from  didv/iios, 
a  twin,  because  it  was  thought  to  be  a  second  silicate  containing  calcium 
carbonate  as  part  of  its  composition.  The  form  was  by  some  blunder  given 
as  didrimite,  but  this  was  soon  changed  by  the  author  himself  to  the  cor- 
rectly derived  form,  didymite,  the  original  v  being  properly  changed  to  y. 
Of  this  word  you  will  find  in  the  books  four  different  forms,  only  one  of 
which  deserves  any  place  in  mineralogy. 

Breithaupt  gave  the  name  kupholit,  from  xov<po?,  light,  and  \iBoS,  to 
a  very  light  variety  of  serpentine.  He  leaves  out  the  o  of  the  original 
word,  probably  because  the  word  koupholite  had  been  used  before,  being 
an  obsolete  synonym  of  prehnite.  This  was  first  changed  to  kuphoite  and 
then  to  cyphoite,  which  gives  little  idea  of  its  original  derivation  and 
meaning. 

Many  more  instances  might  be  cited,  but  enough  has  been  said  to  show 
how  much  confusion  has  arisen  through  carelessness  or  unwarrantable 
assumption,  and  how  desirable  it  is  that  it  should  be  disentangled  as  far  as 
possible. 

In  this  work  the  endeavor  is  made  to  give  complete  information,  as 
outlined  above,  concerning  all  the  names  that  have  ever  been  introduced 
into  the  nomenclature  of  Mineralogy.  Nearly  all  published  works  on  this 
subject  have  been  searched  to  prepare  a  complete  list  of  such  names,  and  all 
available  sources  of  information  have  been  consulted.  Many  facts  have 
been  received  in  private  communications  from  correspondents  at  home  and 
abroad,,  a  list  of  whose  names  is  appended.  But  a  number  of  blanks  still 
remain,  after  years  of  research,  and  the  author  greatly  desires  information 
on  any  of  the  points  lacking. 

A  number  of  personal  names  are  not  given  in  full.  The  use  of  the 
surname  only  has  been  common  with  foreign  writers,  and  in  some  early 
cases  it  is  perhaps  now  impossible  to  complete  them.  One  of  these  is  that 
of  Uttinger,  author  of  the  name  natrocalcite.  A  recent  and  very  re- 
markable case  is  that  of  the  late Adam,  of  Paris,  author  of  the  *  Tab- 
leau Mineralogique,'  Paris,  1869,  and  an  honorary  member  of  the  Societe 
Mineralogique  de  Prance  at  the  time  of  his  death  in  1881.  The  most  per- 
sistent effort  has  failed  to  disclose  his  full  name.  In  answer  to  a  letter  of 
inquiry  on  the  subject  the  venerable  Prof.  Des  Cloizeaux,  his  life-long 
friend,  says:  '  M.  Adam  est  mort  tr^s  vienx,  laissant  une  reniarquable 
collection  de  mineraux  ^  I'Scole  des  Mines  de  Paris.    II  a  toujours  occupe

Words  have  not  been  inserted  under  every  change  of  spelling,  but  only 
those  necessary  to  a  complete  understanding  of  each  case.  Some  of  the 
variations  between  c  and  k,  i  and  y,  and  e,  8  and  t  have  been  omitted. 
>l either  have  forms  in  other  languages  been  included  where  they  are 
simple  translations  of  the  English  names.  Chemical  names  are  also  left 
out,  except  such  as  have  the  sanction  of  use  as  actual  mineral  names.  By 
this  means  the  number  has  been  kept  down  to  the  four  thousand  six  hundred 
and  twenty-seven  names  here  given,  without  omitting,  unless  by  oversight, 
any  that  should  be  found  in  a  work  of  this  character. 

Following  the  Dictionary  proper  is  an  Index  to  the  Authors  of  Mineral 
Names,  which  it  is  believed  will  be  found  of  interest,  as  showing  just  what 
names  each  one  has  given.  It  has  been  found  exceedingly  useful  in  the 
preparation  of  this  work.

includes  under  the  name  several  magnesian  minerals,  particularly  the 
carbonate  and  the  silicate  (meerschuum).  In  1808  D.  L.  O,  Karsten,  Karst. 
Tab.,  48,  confines  the  name  to  the  carbonate,  and  he  has  been  followed  by 
many  mineralogists.  F.  S,  Beudant  in  1824,  Beud.  Min.,  410,  uses  the 
name  giobertite  for  magnesium  carbonate,  and  calls  the  silicate  magnesite, 
p.  379,  in  which  he  has  been  followed  by  most  French  writers.  Carbon- 
ate of  magnesium  usually  more  or  less  mixed  with  the  silicate,  found 
sometimes  crystalline,  but  more  often  in  compact,  white  masses.
